Good. About the image problem: Images work under Windows (see GIMP ;)) but are tricky. You may want to have a look at fpGTK to see where it goes wrong. If that is fixed, the windows/GTK version of lazarus may be used to develop and debug the native Win32 version, which would be a great progress.

Not to mention that then Lazarus is truly cross-platform :-)

Michael.

The bug is essentially that event handlers don't work in Delphi mode. I'm surprised Lazarus hasn't hit it before... It means all units use objfpc mode, probably.

Michael.

Hola, Miguel,

Hey, I didn�t know I can move all these things :-)

I think too the GTK-Windows thing could be the best solution for a working Lazarus on Windows.

Perhaps GTK Widgets don�t look so good as native Windows ones, but I don't mind about it.

I'll be waiting for the gtk windows patches, REALLY anxious ;-)

Thank you all

Miguel

Hi,

I recently discovered this proyect, and as a Win32 programmer, I was a little discouraged reading about the no-usability of Lazarus under Windows, so

1) What is the status for win32 by now ?
2) Can I design and debug on Linux, and then compile on win32 ?
3) Can I compile using gtk widgets on win32 ?

Thank you in advance,

Miguel

Hi all.
First i'll introduce myself: My name is Elio, i have been programming in Delphi and Pascal for a while and just recently switched to Linux and Lazarus. I would love to help in the development of Lazarus, as soon as i get used to it, i hope you'll give me the chance.

I have a couple of questions:

1.- I installed lazarus in my system (Debian) directly from the sources using "make install" and everything goes well. But when i compile the projects Lazarus can't find "Interfaces", "LResource", "Controls", etc. So i guess these units aren't installed. Where should i put them?

2.- How do you make a MDI app? I already have a FSMDIFORM Form and a FSMDICHILD form, but when i run the program, both forms are independent one of the other. Is MDI implemented?

Hmm... I've a running Lazarus :-)
Whithout any image :(
But I compiled my first hello world :)

Today we tried it in my company:

Most demos seem to be in a more or less working state.

The IDE starts, but you can't type anything in the editor. Most dialogs seem to work, although many settings are not saved. (the path to the compiler, for one thing)

You can drop buttons and other components on forms, this works, but since the editor window itself does not work, this functionality is useless.

2) Can I design and debug on Linux, and then compile on win32 ?

This should be possible. As far as the components work, the programs will also work.

3) Can I compile using gtk widgets on win32 ?

Many examples work, but the IDE itself doesn't. For me it's an open issue whether this is due to GTK-for-win32 itself or due to the workings of the LCL. I've written other GTK applications with almost all available widgets (so not just 'Hello world') which work perfectly on windows. This indicates that it's the LCL which is somewhere at fault, but the general opinion of the Lazarus developers is that it is GTK-for-win32 which doesn't work correctly. Judge for yourself.

Michael.

OK, I thought of the old situation, where not in the unit mostly ment not in the dll.

This is, in fact, true for many of the calls that are still between {$ifndef win32}...

OK

I'll try it. Only problem is that we have to build our own gtk unit (again)

What shall I do with the modified gtk unit ?

OK, I've seen them both. The win32 version compiles and runs, but you can't edit.
The GTK version compiles runs etc. but without any graphic. However I didn't commit all needed changes yet.

Cant see why fpc 1.0.10 would give a problem, unless you've hit the bug Michael was talking about.

Marc

We must make a distinction between 'not in the GTK unit' and 'not in the win32 GTK dll'. The former doesn't necessarily imply the latter.

You can uncomment the {$ifndef win32} around the call mentioned above in the GTK unit, because it is definitely present in the gtk dll.

This is, in fact, true for many of the calls that are still between
{$ifndef win32}...

The problem is/was that many of these calls were ifdefed out because the initial win32 version of the GTK dlls indeed didn't have these calls, and this resulted in errors when linking.

But the 1.3 version has almost all calls: fpgtk uses most of them, and all works fine. (fpgtk was developed on windows, so...)

It's not hard to test: comment all the remaining {$ifndef win32}, see which ones you must uncomment again to be able to link your application... If I find time, I will do it myself.

Maybe then lazarus will work on win32 a little faster than expected ;)

Michael.

Yes, we hit it. (e.g. Fri, 25 Jul 2003 10:32:02)
And yes again, the mode was simply changed to objfpc. An no, because there are still 4 units with mode delphi. I will change them ...

Sorry, i have posted my email in spanish.. i dont know why i do that... Well guys if know that GTK v1 is working under windows because i have tryed the
examples thats RAPIDQ have and FPC too and all works fine... and not only that, i have tryed some others examples thats uses GTK and works really good. (not a good look but works ;) ).

Somebody have a workable gtk version or winapi version of lazarus (please..!!!!!!)
as i have comented i making a gpl basic compiler (translator) thats translate from VB to pascal and you can see the source code (good for learn pascal) thats uses the LCL as main GUI Library.

So, thanks to all of you.. :)

I think it is partly due to the missing GTK functions on the win32 lib. Today I tried to compile, but it failed on GTK_WIDGET_SET_APP_PAINTABLE

The "make install" is not complete. Gladfully you don't need it. Lazarus is a development tool and its binaries and sources work together. That means, they should stay in one directory.
So, contrary to most c programs, which require "configure", "make", "make install", lazarus only needs "make".
Just put the lazarus directory wherever you like and do a "make" or "make clean all". Sources and binaries live happily together in one directory.

2.- How do you make a MDI app? I already have a FSMDIFORM Form and a FSMDICHILD form, but when i run the program, both forms are independent one of the other. Is MDI implemented?

MDI is not implemented yet. Any help is welcome.
